My adventures in AS2.0

1

Ok I have a pretty interesting situation… I am trying to use Flash’s BroadcasterMX class to create personalized “onWhatever” listeners for my classes. I got on this rabbit trail by picking apart some of flash’s included classes cough Tween cough… Along with this post is a class I created in order to simulate my own listeners. I will paste the code as well because it is rather short. I am also aware of an ASBroadcaster class (talked about http://www.kirupa.com/developer/actionscript/asbroadcaster2.htm) but just ended up fooling with the BroadcasterMX because that was used in these others as talked about above…

This is my test class:



import mx.transitions.BroadcasterMX;

class Kingdom {
	
	static var __initBroadcaster = BroadcasterMX.initialize (Kingdom.prototype, true);
	
	public var addListener:Function;
	public var removeListener:Function;
	public var broadcastMessage:Function;
	
	private var _listeners:Array;
	
	public function Kingdom() {
		this._listeners = [];
		this.addListener (this);
	}
	
	public function birthKing(name:String):Void {
		var King:MovieClip = _root.createEmptyMovieClip(name, 0);
		this.broadcastMessage("onKingBorn", this);
	}
	
}

and here is its usage:


var myKingdom:Kingdom = new Kingdom();
myKingdom.birthKing("King_Richard");
myKingdom.onKingBorn = function() {
	trace("A king was born!");
}

my problem is that it errors and says “No such property: onKingBorn”… Obviously I am doing something wrong, but my review of its usage in the Tween class proves unhelpful :(… any help?
